The chassis of the Audi TT RS builds on the cutting-edge foundation of the base Audi TT design. The four-link rear suspension, which handles longitudinal and lateral forces separately, plays a crucial role. The electromechanical steering is highly efficient and the power steering adjusts to the vehicle's speed. With aluminum in the front and sheet steel in the back, the body's innovative mixture of materials results in a well-balanced axle-load distribution, excellent crash safety, and the outstanding rigidity which lays the cornerstone for the car's precise handling.
The standard sports chassis, which lowers the body by 10 millimeters (0.39 inches), features tightly tuned springs and shock absorbers. The optional Audi magnetic ride adaptive damping system allows the driver to select one of two modes for the shock absorbers by simply pushing the Sport button. Dynamic mode enables the Audi TT RS to hug the road; Comfort mode provides a pleasantly balanced ride perfect for long journeys.
The sportiest version in the TT model line boasts 18-inch wheels fitted with 245/45 tires. They are complemented by mighty ventilated disc brakes, which measure 370 millimeters (14.57 inches) in diameter at the front and 310 millimeters (12.20 inches) at the rear. So that heat dissipates quickly, the front friction rings are perforated. They, in turn, are connected by hollow pins to the aluminum brake discs, which are encircled by black four-piston brake calipers made of aluminum and bearing RS logos.
The Electronic Stabilization Program (ESP) can be switched off partially or entirely. In Sport mode, the engine does not intervene to monitor traction and, correspondingly, the brakes engage later than otherwise. In the second mode, the ESP is fully deactivated....
